HAND CARTRI DGE- EXTRACTO R.

SPECIFICATION forming part of Letters Patent No. 259,172, dated June 6, 1882.

. Application filed January 18, 1882. (N 0 model.)

To all whom it may concern.-

Be it known that I, DAVID Kraxwoon, a citizen of the United States, residing at Boston, in the county of Suffolk and State ofMassachusetts, have invented certain Improvements in Hand Extractors for Removing Cartridge- Shells from Breech- Loading Fire Arms, of .which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification, in which- Figure lisaperspective view of myimproved hand cartridge-shell extractor. Fig. 2 is a section through the center of the same. Fig. 3 is a plan of the face of the same. Fig. 4 is a section on the line so a: of Fig. 3. Fig.5 represents a modification.

My invention relates to certain im provements in hand extractors for removing cartridgeshells from breech-loadingfire-arms; and itconsists in certain details of construction, as hereinafter set forth and specifically claimed.

My invention has for its object to improve the construction of these implements; and it consists in a hand extractor having one or more of its jaws made adjustable, whereby it can be adapted to fit any sized cartridge-shell, and, if desired, after the j aws have been hooked over the flange at its end, can be clamped or tightened thereon, so as to avoid any possibility of the implement slipping off, as frequently occurs with the old construction if the pull or draft is not in a direct line with the axis of the cartridge-shell or the edges of the jaws have become worn from long use.

In the said drawings, Arepresents the stock or main portion of the implement, which is provided with two stationary hooked jaws, b 0, placed at right angles to each other and adapted to fit over the flange d at the end of a cartridge-shell, B. Directly opposite tothe jaw 12 is placed an adjustable hooked jaw, 0, having on its under side a projection,f, with a dovetailed groove,which slides upon a correspondingly-shaped guide, 9, projecting from the stock A, and at the inner end of this jaw e is a slot, h, in which fits an eccentric pin or projection, 2', formed at the end of the stem 70 of the handle 0, the latter being preferably made in the form of a ring to admit the finger, and thereby afford a convenient hold when the within the stock by some other device. For inimplement is used for pulling out a cartridgeshell from the gun. The stem is fits snugly within an aperture formed for its reception in the stock A, and is confined therein by ascrew, l, which enters a groove or recess inthe stem and allows the latter to be turned on its axis by means of the ring or handle 0. If pre ferred, however, the stem may be confined stance, the stem may be provided with a screwthread fitting a corresponding thread on the interior of the aperture in the stock in which it fits. When the handle 0 is turned to rotate the stem 70 the eccentric pin a, acting on the sides of the slot It, causes the sliding or adjustable jaw e to advance toward the jaw b or recede therefrom, by which means the implement can be instantly adapted to fit any sized cartridge-shell, thus avoiding the necessity of carrying a separate implement for each gun of a difl'erent gage; and, if desired, after the jaws have been hooked over the flange at the end of the cartridge-shell they can be clamped or tightened thereon by turning the handle 0, whereby all possibility of the implement slipping oft, as heretofore, is avoided, together with the necessity of pressing down hard upon the cartridge-shell with the extractor, as was often done with; the old construction, and which frequently caused the metallic end of the cartridgeshell to be broken ofl", leaving the remaining portion still in the gun, to the great annoyance and inconvenience of the sportsman.

The adjustable jaw 0 may be used in combination'with two stationary jaws, as above described, or with one stationary jaw only placed opposite to the movable jaw, in which case the width of each jaw would be made sufficient to prevent any liability of slipping 011' after the jaws have been tightened up by turning the handle; or, if desired, two or all of the jaws may be made adjustable without departing from the spirit of my invention.

In Fig. 5 is represented a modification of my invention in which the adjustable hooked jaw, instead of being made to slide, as above described, is pivoted to the stock A, thus forming a lever which is operated to cause its hooked portion to advance and recede by the conical portion m of the handle 0, which acts upon the tail or lower end of the lever, in which case the stem 70 of the handle must be made to screw in and out of the stock in order that the conical portion at may act properly on the lever.

What I claim as myinvention, and desire to secure by Letters Patent, is-

1. In a hand cartridge-shell extractor, the combination, with one or more stationary hooked jaws, of an adjustable hooked jaw operated by an eccentric pin or projection, i, at the inner end of the stem 70 of the revolving handle 0, working in a transverse slot in the adjustable jaw, substantially as set forth.

2. In a hand cartridge-shell extractor, the stock A, provided with a rotating handle, 0,

and having one or more stationary hooked 15 jaws, in combination with the adjustable hooked jaw e, sliding on a guide, 9, and having a slot, h, for the reception of an eccentric pin or projection, i, at the end of the stem k of the handle (J, by whichitis operated, substantially 20 in the manner and for the purpose described. Witness my hand this 13th day of January,

DAVID KIRKWOOD.
